3313.2 Noncompliant Incident Report

When a blast exceeds established limits such as, but not limited to, ground vibration, airblast, or fly rock, as specified herein, the permit holder shall provide both written (e-mail, fax or hand delivered) and verbal (telephone or in-person) notification to the Fire Marshal or his/her designee using an approved form. The noncompliant incident report shall include all of the following:

1. State what specified limit was exceeded.

2. Complete copies of all seismograph reports showing full wave form time-histories, location of each seismograph and distances between each seismograph and the blast. If claiming a false wind event, a pre-blast noise event report (sensor confirmation test) must be submitted for one event before the actual blast in question, to demonstrate wind influence that may mask actual airblast time histories.

3. Explain why the specified limit was exceeded.

4. Outline corrective measures taken to prevent similar future occurrences.

If the incident caused injury, or damage to property, written notice shall be provided to the Fire Marshal or his/her designee within 1-hour of the time of the blast. This notice shall provide the City with the preliminary seismograph information and a preliminary damage assessment. A follow-up written report detailing the magnitude of the incident shall be provided within 24 hours of the time of the blast.

When a blast exceeds established limits as specified herein, and does not cause injury, or damage to property the permit holder shall file a written noncompliant incident report with the Fire Marshal or his/her designee within 24 hours of the event.

3313.3 Pre-blast Surveys

Pre-blast surveys shall comply with the following:

1. At the time of application for a blasting site permit, the blasting contractor, his designee, or his Certificate of Fitness cardholder may be required to provide written notification to all property owners within an area designated by the Fire Marshal or his/her designee of their eligibility and procedure to request a pre-blast survey, prior to the issuance of a blasting permit. The blasting contractor, his designee, or his Certificate of Fitness cardholder, when required, shall provide a pre-blast survey to all requesting property owners within the area designated by the Blaster in Charge, Fire Marshal, or his/her designee.

2. When a pre-blast survey is conducted a high resolution digital camera shall be used.

3. The individual conducting the survey shall determine the condition of the building and shall document in writing, photographs and any supplemental sketches, any pre-blast damage and other physical factors that could reasonably be affected by the blasting to include the following:

A. Location and size of all existing cracks using a ruler or tape to depict size of crack.

B. Identify all walls and cracks both inside and outside with respect to compass orientation

C. Describe the drainage, (are eves/down spouts away from the building?) type of roof, additions, foundation(s), vegetation and date the year the structure was built.

4. Utilities such as pipelines, cables, transmission lines, cisterns, wells, and other water systems warrant special attention; however, the assessment of these may be limited to surface conditions and other readily available data.

5. The written report of the survey shall be signed and dated by the person who conducted the survey.

6. Copies of pre-blast survey reports and any owner refusals shall be provided to the property owner and/or City of Prescott Fire Department upon request.

The Blaster in Charge shall use a seismograph to monitor each blast to assure compliance with (Figure 1), the Maximum Allowable Peak Particle Velocity versus Blast Vibration Frequency
